She is said to be on the verge of signing a deal for a residency at Las Vegas's Planet Hollywood resort. It is thought that her visit to the city recently was part of continuing negotiations with Caesars Entertainment.

An insider revealed: "Britney has been talking about her hopes to have a baby when her Vegas residency ends.

"They want David to be the stay-at-home dad while she's performing, and says he can't wait to be hands-on.

"Britney's in the best shape she's been in for years. Being with David has really inspired her. He makes her really happy and she wants to look sexy for him," the source explained.
